Make sure the drive is directly connected to the controller before continuing. SCSI and SAS drives are NOT covered in this article.įor general advice on wiping SSD drives, please see Important Notes!! ( information can be found on most desktops & laptops.)
This is ONLY applicable to HDD & SSD drives with Serial ATA (SATA) or Parallel ATA (PATA) interface with a Manufactured Date after 2001. This article will show the user how to use the hdparm Utility to issue the Secure Erase command to an ATA interfaced hard drive. The Secure Erase command writes zeros to the user data portion of traditional hard drives or returns the cells to their original, factory state in solid state drives. This includes both traditional hard disk drives and solid state drives. Since 2001, the Secure Erase command is built into the firmware of the controller on Parallel ATA (PATA) and Serial ATA (SATA) hard drives.
However, traditional whole disk erasing utilities like Darik's Boot and Nuke (DBAN) do not work well with SSDs because the placement of data blocks is not as predictable as traditional magnetic hard disk drives. Solid State Drives (SSDs) are quickly replacing traditional, mechanical, hard disk drives due to their higher speed, lower power consumption, lighter weight, and being more shock proof.
